At random times, I will hear the device removed sound, and moments later a blue screen and reboot. The Vertex 3's are in RAID 0 on the Marvell controller. When the reboot occurs, one of the SSDs disappears. HOWEVER, this is not the cause of it as previously just one Vertex 2 was on the Intel controller and the issue persisted.

Which leaves just the power supply. I'm not too fond of pulling all the wires out to try another. Tried a power supply tester, and it appeared fine. But since it's the only part that hasn't been replaced, could it be causing the issue?
